Within reason, I don't think so.  Let's say your existing cap was 10,000 mfd 63 VDC.  I wouldn't think twice about going up to 100 VDC...but get a lot higher, the can size may be too big, if you can even find a 10,000 mfd 450VDC cap.

Increasing the voltage rating will increase the life of the cap, if all other factors were identical, acording to the cap manufacturers.
