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

Yes

The word "impede" is identical in spelling, meaning, and grammatical function in both Brazilian and Continental Portuguese. The only difference is the pronunciation of the unstressed vowels and the consonants. In Brazilian Portuguese, the final "e" is typically pronounced as a high, bright "i" (e.g., im-PEE-djee), and the "d" is often affricated, sounding like a "dj" sound. In Continental Portuguese, the final "e" is a reduced, closed vowel [ɨ], making the end of the word sound much more clipped or nearly silent (e.g., im-PED).
