At least I can answer this question my self: It is not safe, you can end
up with

2 Modules with one class each

    class mod1::class1($message) {
      $messag = $message
      notice $message 
    }
    class mod2::class2 {
      notice $mod1::class1::message
    }

1 Manifest

    class { 'mod2::class2': }
    class { 'mod1::class1': message => 'Hallo Welt'}

Output

warning: Scope(Class[Mod2::Class2]): Could not look up qualified
variable 'mod1::class1::message'; class mod1::class1 has not been
evaluated at /tmp/modules/mod2/manifests/class2.pp:2
