No, you can not run your Romex wiring in conduits. What you're looking at in the code book is referring to THHN and other wiring, that while insulated with a single coat is not insulated with a second covering and bound to 2 or 3 other wires. Power produces heat and heat is the main problem here.

Conductors entering enclosures within the scope of this article shall be protected from abrasion and shall comply with 312.5(A) through (C). (C) Cables. Where cable is used, each cable shall be secured to the cabinet, cutout box, or meter socket enclosure. Exception: Cables with entirely nonmetallic sheaths shall be permitted to enter the top of a surface-mounted enclosure through one or more nonflexible raceways not less than 450 mm (18 in.) and not more than 3.0 m (10 ft) in length, provided all of the following conditions are met: (a) Each cable is fastened within 300 mm (12 in.), measured along the sheath, of the outer end of the raceway (b) The raceway extends directly above the enclosure and does not penetrate a structural ceiling. (c) A fitting is provided on each end of the raceway to protect the cable(s) from abrasion and the fittings remain accessible after installation. (d) The raceway is sealed or plugged at the outer end using approved means so as to prevent access to the enclosure through the raceway. (e) The cable sheath is continuous through the raceway and extends into the enclosure beyond the fitting not less than 6 mm (1⁄4 in.). (f) The raceway is fastened at its outer end and at other points in accordance with the applicable article. (g) Where installed as conduit or tubing, the cable fill does not exceed the amount that would be permitted for complete conduit or tubing systems by Table 1 of Chapter 9 of this Code and all applicable notes thereto. Informational Note: See Table 1 in Chapter 9, including Note 9, for allowable cable fill in circular raceways. See 310.15(B)(3)(a) for required ampacity reductions for multiple cables installed in a common raceway. The fittings used with NM cable to enter a breaker panel also secure the cable to the panel. When conduit is used, I am not aware of another approved method to secure the cable to the breaker panel as required for conduit runs longer than 10 ft. So practically speaking, you cannot have an entire run of NM-B (or any other non-metallic sheathed cable assembly) enclosed in conduit from a breaker panel because it then limits you to a maximum length of 10ft from a surface-mounted cabinet, cutout box, or meter socket enclosure (including breaker panels/boxes in their definitions). The only direction that NM-B can exit the panel in conduit is out of the top of the panel. The conduit for runs attached directly to the surface-mounted panels also have to be a nonflexible conduit per this clause as well. I believe flexible conduit is out of the picture because it offers no protection from physical damage anyways and that is the primary practical reason to run NM-B in conduit, so you might as well be directly attaching the cable to the breaker panel. This clause also implies that runs of NM-B fully enclosed in conduit attached to a recessed-mount panel are prohibited. I believe this is the same reason that non-flexible conduit is not specified because NM-B should be protected from damage by the wall covering anyway for a recess-mount panel and there is no longer need for non-flexible raceways to protect the cable.
