Yes, if you support in the middle you can go further. 9' would be the max unsupported span. So if you had multiple deck blocks you could go 45' or even further.

Side note spans are not the same across all regions. Make sure to confirm with your local building codes

There are also different span guidelines based on the species of wood being used.
