There shouldn't be (anymore). Do you have any examples of files with that error?
There are a few (I mean few as in probably less than 10 over all of commons) tiff files that don't render that I am aware of, but they don't have that error and instead just time out.

thanks - non-render size up to 50 MP which should get most images in use
but there are still some larger " Error creating thumbnail: Invalid thumbnail parameters or TIFF file

more than 50 MP "

vipscaler might be a solution https://meta.wikimedia.org/wiki/Wikimedia_Blog/Drafts/VipsScaler
Oddly enough, vips scalar was the problem here. There used to be a bug that causes that, its been fixed now (for a long time now), but the old version was cached. If you see any images that are almost entirely white with a bit of black around the edges, do ?action=purge to the image description page.
However there appears to be a second bug ( https://phabricator.wikimedia.org/T116947 ). Rendering the file in sizes less then 2523px seems to be broken.
