Yes — but the combined work must be released under the more restrictive license.
Eclipse Public License 2.0 is a file-level (or library-level) copyleft license. You can include Eclipse Public License 2.0 files in a Creative Commons Zero v1.0 Universal project; the Eclipse Public License 2.0 files retain their copyleft obligation (changes must be released), while the project at large can stay Creative Commons Zero v1.0 Universal. Keep file boundaries clear.

|---|---|---|
| Eclipse Public License 2.0 (EPL-2.0) | weak-copyleft | Yes |
| Creative Commons Zero v1.0 Universal (CC0-1.0) | permissive | No (implicit at most) |
Eclipse Public License 2.0: Module-level copyleft used heavily in the Java ecosystem.
Creative Commons Zero v1.0 Universal: Public-domain dedication; primarily for content but seen on some code.
