Init systems and process managers are meant to be generic, even systemd has that as a goal. The biggest problem is always converting your scripts to a new scheme, unless a compatibility layer exists. On the other hand, package managers are far more opinionated. Each distro has their own particular package format, guidelines and development practices that are made to form a coherent as possible experience. File system layout is important here, among many other things. However, you certainly can. apt-get install yum is a thing. I'm not sure how reliable it is, though.
