In principle yes, but tinc does not offer a way to do that. Also,
reusing a key for another purpose is not recommended. What do you want
to do exactly?

No, because OpenSSL does not support Ed25519 keys. I don't know which
tool can.
Also, even though it looks like PEM encoding, the ed25519.priv file
is actually just a base64 encoded dump of the raw key, there's no ASN.1
involved. I don't know if there is a standard for Ed25519 key formats.
Even OpenSSH's id_ed25519 files don't contain valid ASN.1.
