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

Yes

The word "templo" is identical in meaning, spelling, and grammar in both Brazilian and Continental Portuguese. The only difference is in pronunciation. In Brazilian Portuguese, the vowels tend to be more open and the rhythm of speech is more melodic (syllable-timed). In Continental Portuguese, vowels—especially unstressed ones—are often more closed or reduced, and the rhythm of speech is more stress-timed.
