Hi A!
I'd say it depends on where in the process you got rejected earlier.
If it was at the CV screening - so you didn't get an interview in the first place, I'd be open about it and tell them about the history. If they refer you to HR, this might open a door for another screening.
If you got rejected after an interview, I don't think this referral will help you to get considered again.
In any case, you should be open about the process so far. The partner will eventually hear from HR when they refer you and if that comes at a surprise, that certainly does not put you (and them) in a good position.
