Yes. If the coupon/redeemable has a set amount of expiry days or a set expiry date, that will trump the end date of the campaign.
For example, if a campaign is set to end on 7/1/2020 but the coupon/redeemable is set to expire after 7 days, then if it is awarded on the last day of the campaign, the coupon/redeemable will still be valid for 7 days even after the campaign ended.
