Yes, but I agree with Carl, creating 2 new layers (and modifying current
code in Pcbnew) for a so specific and temporary use is not very useful.

ECO1, ECO2, adhesive layers (rarely used) could be temporary easily
used for this purpose.

I am perhaps wrong, but I am thinking to show an image of existing PCB
on these layers is only temporary, and this image will be removed from
the final board, after placing footprints and routing them.

Yes but not to any other layer:
Edges cut, courtyard layers and some other cannot be used because they
have a special meaning or special properties, and therefore using them
to put a logo on them is a bad idea (bad idea = bug reports, later)
