Yes it is possible however I do not recommendd it.
The reasons for not are:
- SCCM downloads and schedule and executes the SP or CU, but the timing is not exact
- who will verify that all application and user connections have been closed ?
- once the SQL instance is 'quiesced' (no more application and user connections) SCCM will not take a recovery backup of the system and application databases
I could go on but that should be good for starters ...
