Hi Andry,  The warning is a precaution measure to inform users, that it contain System Luns. But they are in RAID config,  Hence  Yes they can be removed. but only one at a time. Also you need to make sure once replace the User must wait for a complete rebuild before replacing any other drive.  Rebuild status can be monitor from Unisphere. and usally take around 8 to 10 hours for complete rebuild.  But make sure you are getting the supported Drives only...
