I have also seen in a thread that this is acceptable to do.

Yes, I do believe you can as you are still going to be at the hotel albeit in another room. Inamuch as I beleive that you can earn points on more than one room booked in your name so long as you are going tot be at the hotel, I think your situation follows that to allow you to use the free cert.
The best way to confirm this is to e-mail the Marriott Concierge and get this in writing and/or failing that, contact the hotel and ask them yourself if you still have any question.
I think any response herein from one of us might be spot on, but you could always find a hotel that is mis-informed and without written assurance from Marriott Concierge or the hotel, itself, our responses still may lack any real weight.
