The short answer, no.
The long answer. Possibly, but it would involve restoring the TSM Server database to a date before the data got expired, audit all the disk storage pools and STG_NEW and STG_DELETE volumes from sequential pools. You will also loose all data backed up after the date you picked for the restore as well as data on volumes that were reclaimed and reused.
Probably too late now, but it's always better to get the retention requirements in writing from the data owners and have them sign off on it. This way, if they come back and ask you to restore data outside the retention, you are covered because they accepted the retention. If they want you to change the retention, no problem as long as they understand it only affects data that is not expired.
