Use Case Diagrams - can actors be within system boundary?

I am developing a software in Java which will run a TFTP Client created as a part of the software and will connect to a TFTP Server which will be external.

My question is should I have the TFTP Client as an actor inside the system boundary using the Actor symbol, as this is something that the system will do? or should I leave it outside the system boundary?

Actors are by definition the things outside of your system with which your system interacts.

So an Actor inside your system boundary would be a contradictio in terminis

It depends on your abstraction level. It is well possible to define actors inside the system under consideration which you represent as the main boundary. Usually if you introduce such actors inside it means that you have sub-systems where those actors interact. So in your case the TFTP is such a sub-system.
