Is the word francesa the same in Brazilian and European Portuguese?

Yes

The spelling, meaning, and grammatical rules for the word "francesa" are identical in both Brazilian and Continental Portuguese. The only difference is pronunciation. In Brazilian Portuguese, the vowels tend to be pronounced more openly and clearly. In Continental Portuguese, vowels (especially unstressed ones) are often reduced or "closed," making them sound much shorter or even nearly silent to a Brazilian ear.
