Usually yes, with some details.  Any recent machine will use mini-PCIe 
wireless cards.  There are full-size 30x51mm and half-size 30x27mm 

IBM/Lenovo and HP have BIOS code that only allows certain cards, 
generally ones they sell.

Atheros AR5BXB63 b/g full-size cards have worked well for me in place of 
Broadcom cards.
