You mean like a language that magick practitioners in every culture can use to comunicate? Or a language that is good to use for spell casting?
For the former, no. For the latter: a lot of people like to use Old or Middle English, Elizabethan English (like Shakespeare and Chaucer, etc) because it has that dramatic, arcane and serious feel. Some people use Latin because a lot of the words we use today come from Latin origin, and so it's like getting to the origin or source of the energy. The reasons for using a different language can range from simple secrecy to tapping into one's "magickal ego", a sort of trigger that tells your brain it's time to get into magick-mode. No language is any more magick than another, so you can even make your own ;D
