Yes, expired domain names can be renewed until the domain name’s deletion date.
If a domain name has the expiration date for example on 2019-06-28 it will after the expiration date be placed in the status “Expired” for 10 days. If no renewal is carried out during these 10 days the status of the domain name will change to "Deactivated" for 60 days. During the "Deactivation" period the domain name can still be renewed but will not be included in the zone file distributed by The Swedish Internet Foundation.
