Not really, you can use DNS to point YouTube.com to an iP you control, but the problem is that you will get TLS issues. It won’t redirect the hostname, but just the IP address. You could use a custom CA and sign YouTube.com certificates, but you will likely still have problems if you use Chrome because they will be pinning certificates for Google services, and your mobile applications will also pin the certs so your mobile YouTube will stop working completely.
