Can I transfer my files from a broken Macbook to a new one?

Hi

I bought two MacBook Air laptops late last year, one of them broke four times, and I finally got a replacement for it.

I just received the new MacBook, and I was wondering if I can somehow transfer my files.

The broken one doesn't boot anymore, so I can't use target disk mode. Also the 2013 SSD drive has a PCIe slot, at as far as I know, there are no available enclosures that support it.

I was thinking of opening the old working laptop and plugging in the SSD drive from the old non working laptop. I would then boot into target disk mode.

Is it safe to do so? They are identical laptops, and I'm guessing the firmware would be the same, but I don't want to risk breaking anything.

Thanks
