Well sort of. You could take the fft then add an amount to the DC (zero frequency) component, then inverse fft. That would have the effect of adding a constant to the image. It's a matter of opinion as to whether you'd call that "filtering" though since no spatial frequencies are altered (other than the zero frequency).
