Could this be used to allow a bigger and faster embedded system share its big screen with smaller boards with no video output through WiFi, or Ethernet where available, so that each one of them receives a portion of the screen, sorta like a quad multiplexer used in CCTV?

In short, yes, but the exact (very long) answer depends on whether you have a gfx-card in the (beefy) 'compute-machine', whether you use X11, or Wayland, Gnome or not, HW-encoding available etc. And that is on the server side. Clientside this also depends on whether you can install arbitrary software, or are limited to e.g. the DLNA-Implementation of e.g. a TV, when it comes to launching/pushing the streams of each quarter. You should be able to use `ffmpeg` or `gstreamer` to construct pipeline(s) to screenrecord, pump out 4 TransportStreams in as-lossless-as-possible-bitrate over UDP, and use DLNA/whatEv to instruct the client devices to display the appropriate stream. If the GFX-Card(s) in the "BeefyPC" can render 4 heads. then this will nearly work ootb with miraclecast.
