Spoke with Forbo Technical and they said that using cork would not work beneath their modular tile, as there would be too much movement up and down which would create issues with the adhesion to the cork. They will not guarantee their product over cork.
What you might want to consider is using a 1/4-in plywood underlayment. You can glue and staple it down and then glue the Marmoleum right over it. This will add some acoustical insulation but according to Forbo the exact amount of sound deadening or impact resistance has not been tested. The company that makes the plywood might be able to provide that information. Another idea might be to use the Forbo Marmoleum Click Cinch Loc planks or squares which are floating floors made with Marmoleum on the top, cork on the bottom and a high density fiberboard (HDF) in the middle. These are ready-made and will provide much better sound deadening than the tile by itself or with plywood beneath it. The Marmoleum Click tiles are 12x12 and the panels are 12x36. They come in dozens of colors and can be creatively designed just like the glue-down tiles but installed much easier and with no glue.
