It’s certainly possible, though it may be difficult to find parts for at this point, since this machine is 10+ years old. I usually recommend checking with lenovo for part numbers, since that helps make sure you’re getting the correct parts. They will often have pictures to reference. I didn’t see the Z560 in this list but it may be identifiable using the exact model number or serial number if you have those.
