The closest to such as thing (i.e. meaningful both genetically and linguistically) are the Indo-European peoples, which are basically all non-Semitic Caucasians. By this standard, Celts, Slavs, as well as Iranians and northern Indians are just as "Aryan" as the Germanic tribes.
By way of that, you probably know that Iran gets its name from around World War II as “land of the Aryans”, to show their solidarity with Hitler. Just a side note.
