With the latest snapshot builds, yes - testing a EA8500 with this recent build now:
LEDE Reboot SNAPSHOT r4589-cb2a391 / LuCI Master (git-17.194.28316-2224714)
Just flashed this week (7/20), so only up for 2 days so far, no issues.
Depending on the Board Rev., flashing without header pins for the Serial TTL -> USB cable is a bit challenging though.
The 17.01.2 release build did not run well on this unit, it locked up.
I would use the 4.9 current snapshot build:

which includes all the excellent work done by the kind folks in this thread:
Still new to all this, so ..
The hardware is good, radio range is excellent / just shy of the WRT1900ACS, but you'll need to crack the case open to flash, and possibly fabricate a header pin adapter as well - the older EA8500 boards have header pins, the later board Revs. do not.
