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

Yes

The spelling, meaning, and grammatical function of "leite" are identical in both Brazilian and Continental Portuguese. The only difference lies in pronunciation:

• In Brazil: The vowels are generally more open and melodic. In many Brazilian regions (such as Rio de Janeiro or São Paulo), the "te" at the end of the word is palatalized, meaning the "t" sounds like "ch" (pronouncing it like leitch-ee).
• In Portugal: The pronunciation is more closed and the unstressed vowels are often reduced. The final "e" is often nearly silent or extremely short, making the word sound more like leit.
