PNG : is it possible to split IDAT?

I have a .png file which contains 1 chunk IDAT.
Is it possible to recompress it to have 2 (or more) chunks IDAT?

Thanks

Re: two different images give no difference!

Both images come from 2 different puzzles on the same theme: in fact something is hidden inside, probably directly in the image. So I am very surprised that ImageMagick makes no difference.

two different images give no difference!

Hello, I have two images which seem to be the same, but MD5 checksums and sizes (445009 octets and 445416 octets) are different. http://imageshack.com/a/img811/1862/gu1m.jpg http://imageshack.com/a/img842/9313/rtqh.jpg I tried to compare the both with ImaheMagick (Compare Program), but I get no diff...
