entity_export - where can it be used?
If the module has been properly written en utilises the full Entity CRUD API there should not be a problem. In most modules this should be the case.

However the Entity module does more (like exposing entities to Views). If the dependency was only used for such a specific case, it might be possible that the module comes with un-exportable entities.

If you want to narrow this down you could search the module for HOOK_entity_info() (change hook to module name) and see what controller class is used. If it is EntityAPIController it is likely to utilise the CRUD API.
