You can play them, both, but they will seriously lower the performance. 4 even more so. I would suggest you be prepared for not only things to run slower in the game(s) but also for your play time to be very limited. You also may experience a bit more overheating when playing them.
While, again, they can be run on a laptop, they are better played on a desktop. Especially if you are (like me LOL) one to add lots of stuff to the game to customize it.
