The motor will draw more than its rated for, if the controller will let it. So if you upped the voltage, you would have to be careful you weren't asking it to do more work than it already can on its stock voltage (ie. top speed, or rate of acceleration) or you could theoretically heat it up and damage it.

EDIT: of course, now that I think of it, the real answer is "it depends". Some motors are more tolerant than others of being over-volted. It's also possible that you could raise the voltage and run it flat out with no ill effects.
