Yes.  This is called a 2nd order factor analysis.  You occasionally see
people repeat the process and do a third order factor analysis.

Of course, you can only do this if you have used an oblique rotation.
If you use an orthogonal rotation (e.g. varimax) then the factors are
uncorrelated, and you cannot refactor them.
