No (if I interpret the question correctly), access to the target is handled on the server side. Although I've seen some feeble attempts to obfuscate the expiry in the link and you might be able to decipher the method of obfuscation, but most are simply looking up the url (which includes a unique token) in a database (or other data store) that maintains the expiry and redirecting the request if not expired or yielding a not found (or maybe a more user friend expiration message) if expired.
But then again I'm a recovering programmer ;)
P.S. If talking about the PlayOn Cloud link, the recordings are only available for 7 days unless you spring for one of their permanent Cloud storage plans at an extra monthly cost.
