Hello, can anyone help me?
I removed some computers from AD and now I can't remove them from Sophos Central, is there any way to remove them?
Thank you for reaching out to the community forum.
You can remove them by going to My Products = Endpoint = Computers = Unmanaged Computers, then select the hostname you wish to delete and delete them. 
What about using:
For Endpoint:
https://cloud.sophos.com/manage/config/settings/auto-delete-computers
For Server:
