If you say "Primary has to check-in", the companion can check in the primary at home or at a kiosk.
The system will still see that the primary has not boarded. DL is strict when it comes to the primary being on the plane or the companion not flying. Otherwise there's still a credit on file for the primary, thus allowing them to rebook. Whereas if the primary flies and the companion doesn't there's no credit for the "companion" ticket since there was no value to it.
If they did what you ask, people would use the companion voucher, book a trip for them and a companion, and then allow the companion to fly, and rebook their ticket for other travel. It would defeat the terms of the voucher.
