PEM_ASN1_read() is largely an internal function used by the library to build the main PEM functions. Its behaviour is not guaranteed in future versions of OpenSSL and could well change. PEM_read_PrivateKey() includes additional functionality to read in various key types automatically such as PKCS#8. If, for example, the default OpenSSL private key format is changed to PKCS#8 (or something else) then applications written using PEM_read_PrivateKey() would still work but those calling PEM_ASN1_read() directly would fail.
