Image name for retina only?

I already know about the concept of iOS apps without retina and retina . But suppose a project created for a retina device, then usually the image name should be "myImageName@2x.png", but can I use it "myImageName.png"instead "myImageName@2x.png"? There are no image size changes, just the image name "myImageName@2x.png"TO has changed "myImageName.png".

Is it really or not?
