Not easily, but if you can program, you can grab (prevent them from passing events to anything but your program) both /dev/input/eventX devices, read keypresses from either, and output them in a single user-defined input device (/dev/uinput).
C example programs on how to use those kernel APIs exist. Other languages are also possible.

The USB Human Interface Device class is standardized, therefore the keyboard should work.
Maybe the fancy features like macros and LED lighting (assuming this keyboard has them) won't work; I couldn't find much info in a cursory search.
