You can technically replace any chip on any device with a better, pin- and voltage- compatible chip. But you need soldering equipment easily tens of thousands of dollars. For example, a Dell desktop I had a while back was the lowest-end SKU, and therefore they left the AGP connector off of the board, even though the BIOS knew about AGP and there were the AGP solder points/vias on the motherboard. Had I had the ability to solder the dozens of points at the same time, I could have added my own AGP slot.
