Early Lease Renewal - any reason not to?

[Fidelis O.]

I have a tenant whose lease expires in September (I know not a good time to have a lease expire especially when you live in Ohio). He has indicated to me that he does not mind renewing his lease early. I also want to keep him and fine with renewing now

Question is - is there any law against renewing lease early that anyone knows? If both landlord and tenant agree to it. Our lease agreement states lease will renew automatically unless they give at least 30 days notice to move. He told me he has no plans to move.
