2018 iMac is completely dead, how can I get files off it

Hi, I have a iMac with under 3 years old that had been working great. Then out of the blue won’t start, no noises no lights completely dead. I’ve tried starting up in recovery but nothing happens just a dead lump of metal and glass. It’s booked in at apple but I desperately need my work files off it. Is there any way to do this without removing HD. I have another mac I can use if this might help
