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

Yes

The word "recebem" is identical in both Brazilian and Continental Portuguese in terms of spelling, grammar (it is the third-person plural present indicative of the verb receber), and meaning. The only difference is pronunciation. In Brazilian Portuguese, vowels tend to be more "open" and articulated, and the rhythm is more syllable-timed. In Continental Portuguese, vowels are more "closed" and unstressed vowels are often reduced or nearly swallowed, creating a more stress-timed rhythm.
