Tough call I suppose. You can take the advice of others here and maybe call the FSDO for clarification, or contact an aviation attorney. There are several valid points for either argument, so clearly it's a gray area.

My thought: it's not worth the trouble for a 10nm flight. What's that going to add to your logbook? 0.3? Maybe 0.5 if you taxi really slow and do a super thorough run-up? Not worth it. And if your employer is pressuring you to do it, take warning. There are likely several commercial rated pilots and CFIs hanging around who are available and willing to ferry this airplane. Why aren't they doing it?
