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

No.

Differences in Usage and Pronunciation The primary difference lies in typical usage. In Brazil, "macarrão" is the generic, standard term used to refer to all types of dried pasta (such as spaghetti, penne, or fusilli). In Portugal, the standard, generic term for the food category is "massa." While a Portuguese person understands what "macarrão" is, they would naturally use "massa" to express the idea of eating pasta, reserving "macarrão" or "esparguete" only when referring to specific shapes.

In terms of pronunciation, Brazilian Portuguese typically features more open vowels and a more melodic, emphasized nasalization of the "~ão" suffix. In Continental Portuguese, the vowels are generally more closed and the nasal sounds are more subtle or "swallowed."
