We are pulling one of our computers out of service. No need to replace it. Can a specific computer’s backup be removed from the remote storage? If so, how?

Yes, it can.
I’m assuming that you have multiple computer’s backing up into the same storage, but each computer has their own backup ID(s). Perhaps only one, perhaps more than one, but unique to that computer.
Let’s say that your computer uses the backup ID Comp1234. Then you proceed as follows:
You can execute the prune from any computer that has access to the storage. However I would make sure that the storage of the computer that is being retired gets wiped, so all the access to that storage is removed for good.
Alternative solution:
prune -a -exhaustive
on the storage to remove orphaned chunks (this will actually free the storage)To be clear: the approach @tangofan has outlined (followed by second prune to actually free space) is the politically and ideologically correct way to do that using the facilities Duplicacy provides and therefor it will always work correctly.
The approach in this comment relies on an implementation detail (that snapshot ids and snapshots map to folders and files) but requires less work and may end up using less time; in addition it will result in the folder being deleted to nothing in the storage reminds of the decommissioned machine.
