Is it possible to use merge tags in the subject of the email?

Yes, you can use merge tags in both the subject and pre-header fields of your emails. This is done the same way as in the body of the email.

You can type your merge tag manually or select it from the drop-down menu. Once you've chosen the target list for the campaign, you'll also see the custom merge tags you've created for that list in the dropdown.

If you select your merge tag from the dropdown, you'll also be able to select what you'd like to display if a contact doesn't have any value assigned to your chosen merge tag.
