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

No

The difference is not just in pronunciation, but in vocabulary. In Brazil, the standard word for fruit or vegetable juice is suco. In Portugal, the standard word is sumo. While a Portuguese person would understand the word "suco" due to the influence of Brazilian media, they would almost never use it in daily conversation, as it is considered a Brazilianism.
