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

Yes

The word "skates" is an anglicism used in both Brazilian and Continental Portuguese with the same meaning (referring to skateboards) and the same spelling. The only difference is in pronunciation. In Brazil, the "e" is typically pronounced as a diphthong, sounding much like the English word "skates" or "skeit." In Portugal, the "e" is much more closed or suppressed, making the word sound closer to "skat."
