We don't know because the "one Sapphire card" policy is new, but based on THIS thread (with different facts), I would say no. You would need to wait awhile before you could change the Freedom to the Reserve. Awhile could be a few billing cycles or longer. Chase reps might not even know, you might simply need to keep asking.

I have never read of anything like this. The card number range that Chase uses for Freedom is likely different than the range they use for Reserve, but it's the account that matters, not the number.
