You most certainly can run Romex in PVC or other conduit per code, but it has some limitations with respect to things like fill factor. This may be done, for example, to provide physical protection to an exposed section of a wire run.
What you can't do is run Romex, or some other "dry locations only" wire, through a conduit and have it magically become suitable for wet or damp locations. Conduit through wet or damp locations, such as outside or underground, requires wires inside it that are suitably rated for that sort of environment. Sometimes people get confused by this and take it to mean it's never permissible to run Romex through conduit since that's one of the primary places where conduit is required in typical residential wiring.
As a practical matter, pulling solid (non-stranded) cable through conduit is often impractically difficult, particularly if there's much other than a pure straight line run. It's just not that flexible.
