It looks like the microwave is a separate entity so yes. Why do you want to replace? Has it failed?

There was a safety recall on something similar a while back, which adds credence to a failed door switch.

Make sure you understand exactly what you are doing if you try to investigate. Microwaves can be LETHAL EVEN AFTER BEING UNPLUGGED
If in ANY doubt at all, ask a Competent Person to look at it.
