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

Yes

The meaning, spelling, and grammatical function of "termina" (the third-person singular present indicative or the second-person singular imperative of the verb terminar) are identical in both Brazilian and Continental Portuguese. The only difference lies in pronunciation. In Brazilian Portuguese, the unstressed final "a" is typically more open and clearly articulated. In Continental Portuguese, unstressed final vowels are often reduced or "swallowed," making the word sound much more clipped and less distinct at the end.
