Yes and no,
yes, Pterodactyl Panel can be installed in Cloudron, no Wings can't be installed in Cloudron.
The question is you should install Pterodactyl on Cloudron, aside from firewall Pterodactyl you will need a lot of dependencies, and because you can use Pterodactyl + Wings on the same server as a start you should.
If you have just 1 node you can also use the hosted free version of Pterodactyl and you will be probably fine, but if you have more than 1 node you want to dedicate all instance to Pterodactyl.
A limitation that you will have is probably the HTTPS on a custom port that cloudron doesn't support at the moment.
