I've run WoW on a laptop with integrated video. You probably won't be able to run much in the way of eye candy, but at 1280x800 (is that really the rez of that laptop) you should be able to play no problem.
I'm assuming that's either a GMA 900 or 950. I've run WoW before on a 1.4 Ghz pentium M with the GMA 900. It looked like crap, but it worked. I would recommend having at least a gig of RAM, though.
