That is a common bench grinder as I would refer to it, not a tool or 
cutter grinder like that used in a tool room.  You certainly could 
through a diamond cup on it if you can find the right size adapters 
and such.  The only precaution is making sure you are holding the 
tool good as you do your grinding.  Sometimes, the cup wheels tend 
to grab more so than the general abrasive wheels.  If you can find a 
cup wheel at a decent price, it sure would be worth it to have. 
Dressing the cup wheel will be your biggest problem as you won't 
have a way to securely hold the point. However, steady hands and 
good eyes can do remarkable things when forced to!

That other grinder sounds facinating!  If you every have your camera 
handy and think of it, shoot a couple pictures for me, I would love 
to see it.
