It should likely work, though I wouldn't consider it the perfect answer.
For comparison, I used Wow on a MacBook Air with an 11-inch display around late 2013. I believe it should work with an iGPU 520 and above. Avoid going into a RAID setup.
900p screen, close to 1080p. If you were okay lowering the resolution to 720p, I don't think the ULV CPU and iGPU would block you from handling more demanding tasks on WOW... Actually, I managed around 30 frames per second in WOW on a basic laptop back then, using just dedicated GPUs like the Nvidia G105M with eight CUDA cores.
