Nope, it's not possible...
Even if you have SW 2015 Service Pack 5, you'll only be able to open 2016 files.
That's because version interoperability is only supported between consecutive releases.

You can export the 2020 file as STEP (or any other universal format you like), then open that in 2015, but you won't have any features.
