So long as the card is half-size mini-PCIe it should be compatible, which includes all the 62xx series, I believe.
I upgraded to the Intel 6230 because I wanted 5GHz WiFi and Bluetooth also, and it works great.
EDIT: Yes, the module in the link is compatible.
One warning though - I've heard of counterfeit Intel modules being sold. Not sure how big a problem it is, but just in case, I'd suggest buying from a seller who stands behind their product(s).
