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

Yes

The only difference between the use of "limpo" in Brazilian Portuguese and Continental Portuguese is pronunciation. The meaning (clean), spelling, and grammatical function (adjective/participle) are identical in both dialects.

In Brazilian Portuguese, the vowels are generally more "open" and melodic, and the final "o" is clearly articulated as a distinct [u] sound. In Continental Portuguese, speakers tend to "reduce" or "swallow" unstressed vowels, meaning the final "o" is much more subtle, shorter, and more closed, often sounding almost like it is being clipped.

4. "A mesa já está limpa." (The table is already clean.)
5. "O chão está bem limpo agora." (The floor is very clean now.)
