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

Yes

The word "termo" is identical in both Brazilian and Continental Portuguese regarding meaning, grammar, and spelling. It can refer to a specific word or concept, a period of time, a legal clause, or the conclusion/end of something. The only difference is pronunciation: Brazilian Portuguese tends to have more open and clearly articulated vowels, whereas Continental Portuguese is characterized by significant vowel reduction, where unstressed vowels are often "swallowed" or shortened.
