Want to create one larger Master presentation and several smaller
sub-presentations with slides linked to the Master. That way I can update
just the master and the sub-presentations get updated automatically.
Powerpoint can link to Excel and Word files, but can see that is will link to
slides in another Powerpoint file.

Yes, this can be done. You'll probably get the most information about this
from the PowerPoint Linking Tutorial:
