For playing BF3 on a laptop you definitely need one that have a built in dedicated GPU, something in the GTX 500M+/HD 6000+ level if you want good FPS on Medium/High setting with no Anti-Alias.
I don't know if BF3 does this(since I haven't seen it during installation), but some game(Like Company of Heroes) would check your PC hardware before installation and refuse to install if your PC don't meet their minimum requirement.
