Can a blue smart charger be used as power supply WHILE charging?

The datasheet mentions it can be used as power supply if not connected to a battery.

But can I also use the charger to power a device while charging a battery, provided that the current draw of the device is significantly less than what the charger is rated for?

Yes, you can put loads on it whilst it is charging.
The loads will reduce the charging current. So if the charger is charging at 4A and the loads are taking 3A then 1A goes to charge the battery.
The Voltage going to the loads will vary and be the same Voltage of the battery at that time.
