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

No

While the spelling and grammar of "entende" are identical in both varieties, there are differences in typical usage, vocabulary preference, and pronunciation.

In Brazil, "entende" is the standard, go-to verb for expressing comprehension. In Portugal, while "entende" is used, the verb perceber is much more frequent when expressing the idea of "understanding" or "grasping" a concept. Additionally, "entender" in Portugal can sometimes carry a nuance of "interpreting" (e.g., how one interprets a specific intention), whereas in Brazil, it is the primary word for both interpreting and understanding.

Regarding pronunciation, Brazilians often reduce the final "e" to an [i] sound (sounding like entendi) and, depending on the region, may palatalize the "t" (sounding like "ch"). In Portugal, the "e" is more likely to be a very short, neutral schwa or nearly silent, and the "t" remains a crisp, dental sound.
