Not really.  When you hibernate, the final action is a power off.  The
hardware is hard reset.  When you resume, it's from a cold start, the
hardware is in a reset state, and the resume process should do a full
reset before actually resuming, to enforce the hardware being in a known
state.  Though, in essence, the resuming will load up a state into the
hardware.

Switching from one OS to the next, with a hibernate in between, will
necessitate a reboot, anyway, as that's going to be the only way that
you'll get a boot choice menu.
