I think you may have misunderstood. I'm not asking if we're allowed to submit links to Elsevier. I'm asking if we're allowed to include a mirror in the comments of an Elsevier submission. This is different from news articles because the news paywalls are only meant to kick in after a bit of usage and are easily avoided by new window or similar, while studies generally require a subscription or paying a fee. The "workaround" for those involves someone with a subscription downloading it and uploading elsewhere, and whether that's allowed on HN wasn't clear from this post.
