Absolutely. Using Alain's settings for radiosity, and, instead of a 

   sphere {
     0, 10e5
         image_map {exr "lilienstein_4k.exr"
         map_type 1 interpolate 2 once}
       finish {emission 2 diffuse 0}

and, adding micro-normals to the cube and the plane:

     normal {granite 0.2 scale 0.001}

I get the attached image.

Note that as the sunlight in the hdr/exr is rather diffuse, the shadows 
are also diffuse.
