In situation where I have access to one ethernet cable between two end
points, is there a way to multiplex so it functions like two independent
(lower bandwidth) ethernet cables?

Perhaps some sort of multiplexer sitting at both end points, each with three
ethernet ports, one goes to the cable, two others are the virtual cable end
points.

Not necessarily. You can buy physical cable splitters which enable you
to run two 10/100 Mbps Ethernet links (each link only needs two pairs)
on one regular four pair Ethernet cable. No switch, no power needed.

Caveats: Obviously will not work for GigE, which uses all four pairs.
May or may not work for 10/100 Mbps Ethernet, depending on distance,
cable quality etc.
