Installing more RAM on laptop than specified, OK?

I have a Dell laptop 5420 laptop in which 16GB of RAM are specified (as a maximum, I guess). However, when I ran "sudo dmidecode -t memory | grep -i max" on the terminal, it output: Page

Maximum Capacity: 32 GB
   Maximum Voltage: 1.5 V
   Maximum Voltage: 1.5 V

If 32GB RAM were installed would it be utilized by the laptop?
