Chinese Wikipedia https://zh.wikipedia.org/wiki/%E7%94%98%E8%82%83%E7%9F%BF%E5... has the coordinates. It's a lot closer to 玉门 than to 嘉峪关.

Edit: nevermind

I don't know if those coordinates are correct. They seem to be the exact coordinates of Jiayuguan City [0], but then the article also says that the 404 site is located "100 km west of Jiayuguan City," with living areas later relocated to Jiayuguan. So I think the article authors just put the Jiayuguan coords there.

40°10′49″N 97°16′36″E is not exactly 39°46′24″N 98°17′18″E. Did you maybe copy the wrong coordinates? Anyways, have an OpenStreetMap link https://www.openstreetmap.org/?#map=11/40.1243/97.3375

You’re right, I think my confusion was that they’re both labeled Kiayukwan in Apple Maps.
