Yes. In fact, most of the time it's better to use BOOST_THROW_EXCEPTION macro.

Yes, as long as the necessary headers reside in Boost.Exception.

I don't see a problem with that. Boost.Exception is extremely lightweight and 
its functionality is often useful when it comes to dealing with exceptions. 
Aside from being a configurability point, BOOST_THROW_EXCEPTION attaches 
position in the code to the exception.
