I assume with "local method" you mean a method that is a member of the 
same class that also defines the transition in its reactions typedef.

No, you cannot. The very semantics UML state machines forbid you to do 
that. If you read everything under

<http://www.boost-consulting.com/boost/libs/statechart/doc/tutorial.html#TransitionActions>

then this should become abundantly clear. That is, at the point where 
the transition action should be called, the state in question has 
already been exited (the state object is destroyed).

I assume you mean the context<> template. If so then the answer is no. 
As the name suggests this template is intended to give you access to a 
context of a given state object.

Could you please explain exactly what you want to achieve? The code you 
have so far with a few comments would go a long way.
