The big challenge is going to be getting the SATA drivers for XP. If you can find those and slip stream it in to your install then you should be able too, just don't expect any TRIM functions or anything.
Really tho, if you need to run XP on a new laptop your best bet is to run it in a virtual machine. Oracle and VMware both offer free products that you could use to run XP. It'll likely make your life much easier.
