NO. Not unless you have a Store.
But since you can fill any orders while travelling, I would suggest that you end all your listings. They will stay in Unsold for up to 90 days.
The day before you return, find a computer and Relist all of the closed item.
You will pay two listing fees, the one you already paid and for the new listing, but that is cheaper in both coin and frustration than having a sale you cannot complete.
