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

Yes

The spelling and grammatical function of "recomenda" are identical in both Brazilian and European Portuguese. The only difference is pronunciation. In Brazilian Portuguese, the vowels are typically more open and clearly articulated. In Continental (European) Portuguese, unstressed vowels—specifically the "e" in the first syllable—are often "reduced" or "devoiced," meaning they are pronounced much more softly or almost disappear entirely.
