I'm not suggesting anyone deceive their employer, but frankly, how would they find out unless you performed the transaction on a company credit card? If I book a flight in dollars, get a receipt, cancel (and get refunded) and then re-book the exact same flight using my miles how would my employer found out? I would have a receipt, and copy of my boarding pass. They wouldn't know to look for any refund or credit.
