Yes the OS 55 manual says you can run those big props and indeed you can, but you will be way off from where this engine makes its best power. Those prop choices are most likely intended to keep the tip speed down for noise reduction which seem to be of great importance in some countries.
Around 14,000 rpm on the ground seems to be a good target for this engine as bob27s has tirelessly been informing us. The APC 11X6 or 10X8 are good choices, listen to the man.
