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

Yes

The word "lê" is the third-person singular present indicative of the verb ler (to read). There are no differences in its meaning, grammar, or spelling between Brazilian and Continental Portuguese. The only difference lies in pronunciation: Brazilian Portuguese tends to pronounce the vowel with more clarity and a slightly more open quality, whereas Continental Portuguese is characterized by more pronounced vowel reduction in unstressed syllables, though the stressed "ê" remains a closed vowel in both dialects.
