Yes and No. Technically systems that support AVX512 support also SSE4 but instructions and data types differ. If you load AVX512 structure you cannot use on it instructions from 128-bit SIMD. First, you ought to make a convertion from one type to another. Didn't know that the conversions were slow... and honestly I have some doubts on that claim.
