No. One of the rules for a new block is that its timestamp is greater than the previous block's.
This applies to all blocks in the canonical chain. I believe uncle blocks may have the same timestamp, since their contents are not part of the canonical chain.

The link you provided discusses this. It is a part of the ethash consensus rules, but other consensus engines like clique don't necessarily have the same constraints.– AusIVApr 3, 2022 at 12:40
