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

Yes

The word "acordado" is identical in both Brazilian and Continental Portuguese in terms of meaning, spelling, and grammar. It functions as the past participle of the verb acordar, serving as an adjective to mean "awake" (the opposite of asleep) or as a passive participle to mean "agreed upon" or "settled" (in a legal or formal context). The only difference is pronunciation: in Continental Portuguese, unstressed vowels—particularly the initial "a" and the final "o"—tend to be much more reduced or "closed" compared to the more open pronunciation typically found in Brazilian Portuguese.
