No. High Sierra was the last version with support for this, and the iMac 2015 is too new an iMac for target display mode.

In short, Mr. Hoffman is dead on correct. If you need an external display you need to buy one. If you want to share an external display between the two iMacs I would recommend contacting OWC (www.macsales.com) and see what type of solutions they may have.
