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

Yes.

The difference between the use of "corredor" in Brazil and Portugal is strictly phonetic. In Brazilian Portuguese, vowels are generally more open and clearly articulated. In Continental Portuguese, unstressed vowels are frequently reduced; specifically, the "o" in the final syllable of "corredor" is typically pronounced as a closed "u" sound ([ko-re-ˈdoɾ]). The spelling, meaning, and grammatical function of the word remain identical in both dialects.

Brazilian Portuguese Examples

3. Não corre no corredor, você pode cair! (Don't run in the hallway, you might fall!)
4. O corredor de atletismo é de borracha. (The running track/lane is made of rubber.)
