No, not until the PC is able to emulate the Xbox360. It's possible that much further in to the future this will happen. However, for now.. Chances are very slim. That is unless a supports both platforms.. PC and Xbox360.
You can't. They don't exist. If you really want an XBox360 based laptop, you'll have to heavily modify an existing console, which would not only invalidate the warranty, but is also not 100% guaranteed to work.
