The Lion did not betray the Emperor. Period.

We are talking about events where the word "Betray" has sharp and clean edges like a blade. Betray means to turn your legion against the Emperor, give yourself to Chaos and aiming at the destruction of the Imperium,  at the side of Horus. During the HH, whoever did not do that is not a traitor.

On the other hand, many actions taken by the Lion have shadows, could raise doubts, could be classified as quite distant from other "utterly loyal" legions like Ultramarines or White Scars, or Imperial Fists and how they behave during HH. But all of this, in the end, does not count. Because accusations are very specific, and the Lion does not fit the "Official HH traitor Primarch" identikit.
