If you're asking does your 121 SIC count towards upgrade requirements at a different airline, then yes. Once you have it (after the cutoff date in the rule), it's totally portable. What you do in the meantime doesn't matter.
Individual airlines can (and some do, or used to anyway) require X amount of hours at that company to upgrade.
