Yes through the PCI bus not directly. You don't want to have that latency. You want a unified model. Like Intel GPUs that can access main memory, or the FPGA being another endpoint in AMDs infinite fabric architecture. That exists as well in SoCFPGA boards. But not in the mid or high performance segments.

Back when AMD released the first Opteron CPUs there was a vendor selling an FPGA that would plug into an Opteron socket along with the IP to implement HyperTransport in the FPGA.

Really? I used a HT FPGA back then, but it came on an HTX card that fit into the HTX slot on the motherboard.

Never heard of putting it into the socket, would be a real pain to attach JTAG to program/debug your design...
