Extrapolating from one contractor license to another, even within one government agency, is not a good idea. Doing between agencies is just not possible. Over the past ten years we have had 10 contracts with DOE, EPA and USFWS. Every one of those had different specifications regarding equipment use and software use. None stated that the usage was limited to only the specific contract work. If it had, the contracts would never had been signed. Your contract may be different but there is no one specific contract so your generalization does not appear to be correct.
