Charging it with laptop charger?

Hello, I have a Samsung Galaxy Tab S2 (yes, old but so much better than there new stuff) and would like to know if I can use my Lenovo Yoga charger for the tablet too.

The laptop charger is a standard USB output, so I can just swap devise charging cables. The charger say its output is 20V @ 2A or 5.2V @ 2A. The charger I have for the tablet says 5V @ 2.4A max.

I'd like to only carry 1 charger if possible, but don't want to do any damage to the tablet.

Thanks!!!
