I do the laptop thing here, and it works just fine w/o troubles. Yes, you can copy the runtime over whole and it'll work just fine. The only thing I'dadd is to make sure you have a decent OpenGL-capable video card (NVIDIA, ATI... Intel's video chips suck mud still).

My own specs are as follows:

Model: Samsung RC512-S2

Core i7 2630QM

8GB DDR3 RAM (it came with 6, and I bumped it).

NVIDIA 525M Video card

750GB HDD

Multi-touch trackpad, 15.6" screen (1366x768)

Windows 7 x64 (though this is usbject to change).
