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

Yes

The only difference between the word "crus" in Brazilian Portuguese and Continental Portuguese is pronunciation. In most regions of Brazil, the "s" at the end of the word is pronounced as a voiceless alveolar fricative [s], similar to the "s" in the English word "sun." In Continental Portuguese, the "s" is typically pronounced as a voiceless postalveolar fricative [ʃ], similar to the "sh" in the English word "shoe." The spelling, meaning, and grammatical function of the word remain identical.
