I guess yes you can.

Yes, you can use that key, but make sure, that you install the version which was bundled, or mentioned over there(on the back of laptop). Like generally lappy's comes with Win 7 Home, so if you install Win 7 Ultimate and use that key, it won't work.

Yeah, you'll probably have got a recovery disc with the Laptop, use it to install the OS again.
