No, if you wanted to load a configuration file called config2.php, you'd have to either autoload it, or load it manually with:
Code:
$this->load->config('config2');
Then you'd access it the same way:
Code:
$this->config->item('site_title'); # etc...
Anything in the application directory is yours to edit as you see fit. Therefore, it might make more sense to put it on into the existing config.php, as it will save a disk read, and it's already loaded for you.
