No. The execution of actor gets scheduled. It is very dangerous to use any kind of fast path there. Consider a chain of communicating actors. If there is a fast-path on send and they are all running in the same context, then the stack usage will be proportional to the length of the communication chain. It would be very timing-dependent and could blow up with StackOverflow and the very unexpected and random moment.
