yes

simply jump to it : this_context.jump_to( original_context);

It is the base of coroutine, fiber etc. The libraries build on top of 
boost.context usualy provide more functionality like scheduling, result

You can build your own cooperative scheduling libraries (coroutine and 
fiber are only examples) with boost.context.
