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

Yes

The word "pinta" is semantically, grammatically, and orthographically identical in both Brazilian and Continental Portuguese. It can refer to a mole (on the skin), a small spot or speck, or be the third-person singular conjugation of the verb pintar (to paint). The only difference is pronunciation: in Brazilian Portuguese, the unstressed final "a" is typically pronounced as a more open, central vowel [ɐ], whereas in Continental Portuguese, this vowel is often more closed or heavily reduced, sometimes sounding almost like a silent or whispered "e" [ə] depending on the regional accent.
