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

Yes

The word igual is identical in spelling, meaning, and grammatical function in both Brazilian and Continental Portuguese. The only difference lies in pronunciation:

• Brazilian Portuguese: The final "l" is vocalized, meaning it sounds like a "u". It is pronounced as /i.ɡwˈaw/.
  • Continental Portuguese: The final "l" is a "dark L" (velarized), where the back of the tongue is raised toward the soft palate. It is pronounced as /i.ɡwˈal/.
