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

No

While the spelling, grammar, and fundamental meaning of "trabalhado" (the past participle of the verb trabalhar) are identical in both dialects, there is a difference in typical usage and pronunciation.

• Usage: In Brazil, "trabalhado" is frequently used as an adjective to describe something that is "elaborate," "intricate," or "highly styled" (such as food, hair, or art). While a person from Portugal will understand this, they are much more likely to use words like elaborado, detalhado, or cuidado to express the same idea.
• Pronunciation: The phonetic realization differs significantly. Brazilian Portuguese features more open, clear vowels and a more melodic rhythm. In Continental Portuguese, unstressed vowels are much more closed, reduced, or almost swallowed, making the word sound more "clipped."
