Unfortunately, there is no easy way on the CSM to clear or archive configurations, it has to be done by hand. I would suggest copying the running configuration to the disk/bootflash on the sup (copy running disk0:backup.cfg), then deleting the configuration you want to remove. If you need to rollback the config, you can just do a "copy disk0:backup.cfg running-config".
Sidenote - A lot of people ask about the command "clear module csm linecard-configuration". All it does is force the CSM to re-download a copy of the configuration stored on the MSFC to its own flash chip. This does not delete the configuration on the MSFC itself unfortunately.
