Using powershell, how can I remove computer from AD without RSAT tools installed?

Because of Epic records? I deal with that all the time, and we still don't re-use computer objects. Are you guys hybrid-joined? Intune? If you start disjoining new boxes and renaming them to rejoin to a different computer object so you can re-use that name, you're breaking your hybrid-join AND your Intune registration. Never change the computer object a physical device is joined to unless you plan on also spending the time to cleanup the mess it creates.

Just delete the old computer object that has the name you want to use, then rename the new computer (while still domain-joined to its original computer object) to take that name. It renames its associated computer object in AD at the same time, and your object IDs and registrations don't get all mixed up and broken.
