I have a laptop that's probably about the same as yours. I can play the game but it's far from optimal. The video card can't handle the video so there's a dark line about an inch and a half along the horizon. If a plane is close enough to you in the middle of the screen you'll see him but the rest of the horizon is all dark. You'll also get low frame rates.
You probably won't be able to play on battery power. If I started up the game on battery it would just sit there, frozen. You couldn't play it. Cooling might be an issue, too. The only time I ever heard the fan go on in my laptop was when I'd start up Aces High. I wouldn't even have to start playing, just starting the game would cause the fan to go on. I never had an overheating problem that I knew of but I suppose it could happen to other laptops.
Despite all the above, I played for some months on my laptop and actually improved my game. Once I got my Alienware system up and running again, I stopped using the laptop for the game entirely. There's just no going back from an Alienware.
About the only way to know for sure if your system will handle it is to do what I did and give it a try.
