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

Yes

The only difference between the word in Brazilian Portuguese and Continental Portuguese is the pronunciation.

In Brazilian Portuguese, the "l" at the end of the word is vocalized, meaning it sounds like a "u" (e.g., ter-mi-nau). In Continental Portuguese, the "l" is a "dark l" (velarized), where the back of the tongue approaches the soft palate, making the "l" sound much more distinct and heavy.
