Yes, provided you equip that MS-DOS with a DPMI server of some kind.
CWSDPMI, usually.  The executable doesn't know on what platform it'll
run.

The difference is where you want to run DJGPP itself, mainly, not
where the programs made it will be running.

No.  It does essentially nothing on XP.  You'll need to keep it at
hand to be able to run anything on DOS, though.  So download
csdpmi5b.zip and keep it for later, when you'll be installing that
program on raw MSDOS.
