One of my two 4GB Kingston HyperX DIMMs just died. I have the original 4GB Lenovo DIMM that came with the X220. Can I slot that in with the Kingston?

Absolutely.

For best performance and compatibility it's always best to use RAM modules of the same rated speed and timings. However, like ZaZ said there should be no problems using the DIMM originally shipped with your laptop.
Only difference will be that you may find the timings on the factory DIMMs are not as good as the Hyper X but I hardly think you will notice the difference in day to day tasks.
Mixing DIMMS?
