Can't speak specifically to the 26" model, but I have wall-mounted my UN32EH4000 32" Samsung which sppears to be the same series in a different size. I used the AmazonBasics Articulating Universal wall mount and it works fine. Good luck!
Yes you can wall mount this but you need to get the wal mount bracket seperately however It comes with the wall bracket to tv screws but not the wall mount to wall screws which should come with the wall mount.
According to my user manual, my TV can be wall-mounted with purchase of a wall mount kit. However, my model number though is UN32EH4000, not the 26" model. I suggest you call the Samsung customer number to confirm.
