    Probably not. From the drawing, it looks to merely be a digitally controlled stereo audio amplifier.

    You have three separate posts asking about taking IC's from used equipment to play MP3's.

    This is simply not practical. Assuming the equipment has a true MP3 decoder IC and is not already designed to play MP3's from an SD card, you'd have to design your own PCB, add a microcontroller to interface between the MP3 decoder IC and the SD card, and write code for the microcontroller. You'll also probably need a pre-amplifier so you can hear the MP3's through headphones or a speaker.

    If you simply want to hack your used equipment, this would be a different story. You could easily add wires to the CD player, for instance, and use other buttons or controls to play the track you want, pause, etc.

    If you want to play MP3's off a micro-SD card, I'd suggest a pre-made module such as this. This is designed to be used with a microcontroller as well, but if you look at the datasheet (attached), you can use certain pins to control the module directly without needing a microcontroller. I think you'll need to make or break a jumper connection somewhere though.
