If it is not hostless, it may not be supported directly. But I suggest that you choose one router which has ROOter firmware, like AR150, AR750, AR750s etc. so at least you will have ROOter firmware to use.
btw, Is EM7455 has anything in common with MC7455, which is their PCIe module. It is supported in all of our 4G routers by default.
