Terpeion Mount obtained on wrong region


I have an issue regarding the Terpeion mount reward. This reward was apparently obtainable since yesterday on EU Central region but it did not appear so for me. Out of curiosity I checked the EU West region and to my surprise it was there. So I did claim it without much thinking (as I do with all rewards) since I assumed I will also be able to get it on my main character in EU Central.

Turns out just now, that this reward is only obtainable once per account, not region specific.

Can you simply transfer the mount from my level 1 character from EU West region (that I have no intention to play) to my main character in EU Central?
