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

No

While the literal definition of "beleza" (beauty) is identical in both dialects, there is a significant difference in usage. In Brazilian Portuguese, "beleza" is a ubiquitous slang term used as an interjection. It can function as a greeting, a way to say "okay" or "alack," a way to confirm understanding, or a way to say something is "cool" or "great." In Portugal, using "beleza" in this way is very rare and would be immediately recognized as a Brazilianism. A person from Portugal would instead use words like "está bem," "tudo bem," or "fixe" to convey the same meanings.
