Theoretically, yes, but may be painful. I did it when moving from 2.3 on 16.4 to 2.4 on 18.04. You must be very comfortable with ubuntu administrating and be brave enouth.
Do this only if you have no option for fresh install, or if you just like challenges.
Steps to do:
1. backup the whole /var/bigbluebutton, greenlight install directory, and all bbb/freeswitch/kurento configs. Dump and backup greenlight postgres database.
Now, you need to keep the greenlight installation files (in the greenlight directory), keep the /var/bigbluebutton directory, and get rid of all other files and packages installed by bbb.
2. remove all packages installed with bbb listed by dpkg -l |grep bigbluebutton;dpkg -l |grep bbb; dpkg -l |grep kms;
3. remove libreoffice and java docker images. It seems that greenlight/postgres images can be kept.
4. remove all apt repositories in /etc/apt installed by bbb
5. upgrade your system with do-release-upgrade
6. cross your fingers, and install new bbb as documented
7. apply your custom configs saved in backups
8. If you are lucky, you are done with new bbb. All you rooms, users and recordings are there.
9 if something went wrong, double-check for old packages and files which do not belong to ubuntu 20.4, remove them, and reinstall bbb
10. if nothing helps, make clean install of Ubuntu 20.04, clean install of bbb, and restore your data from backups.
Once again, do it only if you know what to do in the disaster case. Good luck!

Vasyl
