Does an iron core increase the total energy stored in a coil?

Yes, an iron core increases the inductance of a coil, and at any given exciting current, that also increases the stored energy. Ferromagnetic materials (iron being the most familiar) do not merely channel the field, but take on polarization (which is effectively extra circulating current that does not go through the external electric circuit).
