Every SREL update via "updateObject" will use the id. It's the foreign key. So the short answer is NO.
The long answer is : If you use PAM, create a custom operator that does the lookup with the name for you. If you use another programming language, you can always code a custom web service who does the lookup.
Something like
In house application doing customUpdateObject into -> custom webService that asks for name instead of ID. Will lookup for the id and call -> SDM webservice updateObject.
