Can I use a Forgotten Realms Adventure League Character in an Eberron AL Game?

Getting reading for GenCon and I’ve got a Lvl 5 Lizardfolk Paladin that I’d like to use in a series of Eberron games at GenCon. Other than some cursory googling, I don’t know much about Eberron besides that it’s pulpy, steam-punk DnD. I’ve been looking for something different and this sounds right up my alley.

I wonder if this particular character is the best fit for the setting though. From what I’ve read, deities work differently in Eberron. Would there be any reason, thematically and/or rules-wise, that a GM wouldn’t let me use this character?
