not really. Iartă-mă = forgive me, scuză-mă = it's a mild form of "Iartă-mă" something like - excuse me / I'm sorry. we usually say "pardon" when is a crowded place and we need to pass through, or we accidentally bump into people. For example: Te rog, iartă-mă ca te-am mințit - Please, forgive me for lying to you. Scuză-mă că am întârziat, nu am auzit alarma. - I'm sorry for being late, I did not hear the alarm. Scuză-mă! Pot să te întreb ceva? - Excuse me! Can I ask you something?
