This is unfortunately not always true, even with a table-based unwinder. In order to detect the noexcept frame and call terminate(), the unwinder must be able to see the stack frame that has noexcept. This means that the compiler must suppress tail call optimization when a noexcept function tail calls a non-noexcept function.
