The answer is no, only 2019 and 2022 currently, see MPN Benefits - Technical Support for On-premises or Cloud products - Partner Center | Microsoft Docs
You can use the MPN benefit Microsoft Product Support for technical support requests for recent on-premises product versions only. Recent on-premises products include only the current product (N) and the previous product version (N-1). The previous product version is only supported if it is within mainstream support ; based on the N-1 support policy. For non supported products and versions, use the relevant paid support option or purchase a Partner support plan.
