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

Yes.

The word "tricotar" is identical in meaning, spelling, and grammatical function in both Brazilian and Continental Portuguese. The only difference lies in pronunciation. In Brazilian Portuguese, the vowels are generally more open and clearly articulated. In Continental Portuguese, unstressed vowels are often "reduced" or clipped, which can make the word sound shorter or more swallowed to an untrained ear.
