Yes.

You can define BOOST_EXCEPTION_DISABLE, which disables the Boost
Exception library itself, leaving the legacy boost::throw_exception
behavior (which still has two flavors, depending on
BOOST_NO_EXCEPTIONS). In this configuration no STL components are used
except for std::exception. You can then #ifdef your code that uses the
Boost Exception library with BOOST_EXCEPTION_DISABLE.
