can I use a 16vac 300ma unregulated AC-AC adapter to replace a 16vac 250ma one?

You certainly can. The current rating is just the max you can get out of it, not what will be forced into the equipment. The equipment just takes what it needs.

I know, but the voltage is higher because of the smaller load :
From the datasheet, it shows that it will output 17VAC @ 250mA load.

The equpt. will take what it needs, but the supply might burn it, what I don't want

The regulation (amount the voltage sags under load) difference between a 250mA one and a 300mA one will be pretty small, so I say you will be fine.
