Yes, it is possible but requires that you enable developer mode, and you then can install crouton via commands in a terminal window as explained here:

https://www.howtogeek.com/162120/how-to-install-ubuntu-linux-on-your-chromebook-with-crouton/

After that you can install openjdk using this command in terminal:

sudo apt-get install openjdk-8-jre

and then download and run the kojo jar-file from terminal using this command:

java -jar xxx.jar

where xxx.jar is replaced by the name of the downloaded kojo jar-file from here:

If you have problems, your IT-department should be able to help you with the installation.
Good luck!
