I have an LG 710 4k projector with earc and want to have a hdmi connection to my projectors earc output, I’ve tried a 25’ hirez hdmi from the projector to the arc but it is not recognized . Is it possible to connect a beam located at the back of the room with the projector to the supplied Sonos short cable to my projectors earc and pair the beam in the app to my arc located under my 106” screen ? Would the arc be recognized as the main soundbar and beam be seen as a surround even if it were to pair ?

No, that would not work, a grouped Arc would play in stereo only, with all channels downmixed to 2.0 and delayed by 75ms.  You need a physical HDMI connection between the Arc and the source.

Generally, standard HDMI cable performance tends to drop off after 25 feet.  Over that, you need to look into an active cable, like this one: 8K Fiber Optic HDMI 2.1 Cable 50ft, Long Active HDMI Cable
