Not for naming it that, but for falsely implying the existence of an explosive device on the plane.
So I guess it would count as carrying a dangerous explosive device.
I grant that basically any large lithium batter can do the same (or be induced to do the same), but this one was both common and could go off accidentally, making it a more common and therefore likely threat.
Suggesting that someone go to jail over "SSID naming convention contains Note 7" is absurd.
This is definitely a description of what happens to the batteries.
