CVR pt 91?

Can two non-SP rated CE-525 pilots fly as pilot and copilot on a part 91 flight without a cvr?

The reason I ask is because a flight department I am associated with has two non single-pilot rated Ce525 people and we are told they cannot fly together unless there is a cockpit voice recorder installed. Frankly I think it is a waste of resources to buy another $10,000.00 box... that money should be properly spent to upgrade both pilots to SP, imo.
