I think it depends. You could use this to see if a project file has been opened:

if (app.project.file == null){
  // no project file open
}else{
  // project file open
}

But that won't work in the case where you've opened a project file that had to be converted from an older version of AE, so there's technically no project file associated with the converted project. It might work for you though, depending on what your requirements are.
