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

Yes

The word "licença" is identical in meaning, spelling, and grammatical function in both Brazilian and Continental Portuguese. The primary difference is pronunciation. In Brazilian Portuguese, the vowels are generally more "open" and clearly articulated (for example, the "ê" in licença is pronounced with a distinct, open sound). In Continental Portuguese, vowels are often "closed" or reduced, which can make the word sound more clipped or even swallowed to a Brazilian ear.
