I would like to say yes but, if it's a comment being restored containing personally identifiable information of the person that deleted it than I would say no. With that said I believe you need to have a formal request to remove PII and I have some doubts if deleting or obfuscating a reddit comment you made qualifies as such.
GDPR is principles-based regulation. No specific thing you mentioned actually matters, what matters is whether anyone's privacy rights will be violated by rolling back years worth of deletes or edits.
