If it's possible to call Fortran from C, yes.
Just declare the function with the FFI like you'd do it in C.

If the call protocol of your Fortran compiler is different than that
of your C compiler, then something might still be possible, using a
library like ffcall/avcall (used by clisp, I don't know if cmucl uses
it too, but you could write a FFI to that library to then write the
FFI to the Fortran call protocol).
