Yes, nothing of BC115 is particular except no complement, only low gain, low dissipation and Ft 80mHz.
As an audio driver, you might look to more modern high voltage types (BC546/56 as listed by Wahab or 2n5401/5551 etc.) in an effort to limit Hfe to original part spec, if there is a stability issue in your application.
Something non-RF guys often neglect is the sensitivity of audio circuits to RF. High gain/Ft audio parts where they are not strictly needed can cause mayhem and QRP transmitters, for example, are notorious for such problems where RF and AF circuits are in close proximity and poorly shielded IME.
