It'll be fine. It's actually a better bet than a guitar amp - the sound spectrum is far wider. It's the choce of several electronic drummers I know. The obvious is that you'll wreck any amp (specifically the speaker) by playing it way too loud.
I used a Carlsboro Viper (15" speaker, no tweeter) 100w in the studio for a good few years with electronic drums, with no problems, and it sounded good.
