Black Templars are fist successors but you wouldn't know from looking. Therefore if salamanders fit the fluff, go with it.
I've been saying this for a while since the Chapter Tactics rumors first started, these rules are brand new. A month old right now.

Don't let an arbirtrary set of rules written down by GW affect how you play your army on the tabletop. You can write their fluff as Imperial Fists successors, and then use Salamanders fluff on the table if you want to.
