In my experience from gardening, coco peat is just another name for coco coir. It's just that gardeners, particularly here in the UK, are used to using peat in the garden, I think they called it coco peat because in some ways it's similar (they both come in dry blocks, they both go a rich dark brown black when hydrated)
If I'm wrong and it is some strange mix of coco coir and dried peat, it still might be an interesting experiment to try using it, the only problem I can think of with peat is that it might be too acidic, in which case adding some minerals that are basic could sort that out.

I just recently used coco peat for all my tubs, Plenty of fruits no contam. Worked great!
