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

No.

While the spelling, grammar, and literal meaning of "salteados" are identical in both dialects, there is a difference in typical usage. In Brazil, "salteados" is often used specifically to refer to "stir-fry" style dishes (frequently of Asian origin) or more "gourmet" culinary preparations. For everyday cooking—such as sautéing onions, garlic, or vegetables in a pan—Brazilians much more commonly use the word refogados. In Portugal, "salteados" is the standard, everyday term for any food prepared using this method.
