When I hear "emulation," I think "in software, a la Turing-completeness."

It's like saying a Volkswagen "emulates" a Model-T. It drives on the same roads, but the internal implementation is quite different.

Whether it’s a program running on a CPU that interprets software written for the original device, or a configuration of look-up-tables in an FPGA that can interpret software written for the original device, it’s still a system that intends to exactly reproduce the behavior of another one. I’d call that emulation.
