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

No.

While the meaning and spelling of "vende" are identical in both dialects, there is a difference in typical usage. In Brazil, the second-person singular imperative (the command "sell!") is rarely used because "você" is the standard pronoun for most social interactions, which requires the third-person form "venda." In Portugal, the use of "tu" is the standard for informal address, making "vende" a very common way to issue commands.
