Not safely. Because the coroutine it refers to might by dead (either ended or in an error state). If you want to do this, create a new coroutine in your c library (anchor it in the registry), solely for the purpose of callbacks.
Make sure to call it only using protected calls to prevent it from accidentally dying in an error state (and don't call it after the mainthread/luastate ended).
