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

Yes

The word "pequenas" is identical in meaning, grammar, and spelling in both Brazilian and Continental Portuguese. The only difference lies in pronunciation.

In Brazilian Portuguese, the vowels are generally more open and clearly articulated. The "e" in pequenas is typically pronounced as an open /ɛ/. In Continental Portuguese, speakers tend to "reduce" or "swallow" unstressed vowels. This means the "e" might sound more closed or even nearly neutralized, and the final "a" may be less emphasized, resulting in a more clipped, rhythmic sound.
