Gee, I would hope so.
But; I ain't seen it.

The Far-Reaching Realms of Denisovan Ancestry Stretch to Iceland
https://www.ancient-origins.net/news-evolution-human-origins/denisovan-ancestry-0013617
INTRO: This week it was announced that a new genetic study published in the journal Nature shows that the genomes of over 27,000 Icelanders display an admixture of modern human and Neanderthal DNA, along with a noticeable trace of Denisovan ancestry that was not expected at all. These findings suggest that past introgression took place between the direct ancestors of Icelanders, most obviously archaic Norwegians, and either Neanderthals carrying Denisovan DNA or Neanderthals and Denisovans separately. Similar results have not been noted in modern-day Scandinavians, either due to insufficient study of their genomes, or the fact that any residual Denisovan DNA has been diluted through interbreeding with other European groups with no traceable Denisovan ancestry.

One speculative possibility: Norwegians have a high incidence of Yamnaya DNA. The Yamnaya might have mingled with East Asians carrying remnant Denisovan genes. If Vikings from Norway primarily settled Iceland, that island was more isolated than Norway. Norwegians would have intermarried with other population groups over the following centuries, perhaps drowning out any Denisovan legacy they previously had.

Siberian origins are still present in the Sámi people (i.e., human carriers of remnant Denisovan genes might have abided in some ancient Siberian populations). But the Sámi didn't settle in Iceland. Unless you go by this potentially wild hypothesis, that they traveled there even before the Norway Vikings. Even if that was the case, they presumably died out or departed later.

Denisovans in Iceland ...
I wouldn't rule it out.
However, it does not seem to be the most likely vector.
If so, then, perhaps look to mis 3 as the time of travel.

Ancient DNA shows Sami and Finns share identical Siberian genes
https://www.helsinki.fi/en/news/lif...sami-and-finns-share-identical-siberian-genes
The Finns reportedly have a minor degree of Denisovan genes, but this claim might be purely inferred from their partial East Asian ancestry, rather than direct testing:
https://www.cell.com/cell/pdf/S0092-8674(18)30175-2.pdf
"... the previous finding of Denisovan admixture in Papuans and in Asians. Figures 4 and 5 also indicate that several other populations may carry a small proportion of segments introgressed from Denisovans. These include the Finns, who are estimated to have obtained around 7% of their ancestry from East Asia, and admixed American populations whose Native American ancestors are related to East Asians."
Even though the Sami have been subject to genetic research, there's nothing about Denisovan heritage showing up (though perhaps no one was directly looking for that).
Today, supposedly half the Sami people live in Norway. While Vikings and the Sami did interact sometimes peacefully during the medieval era (when Iceland was settled), they remained distinct communities...

Denisovans themselves disappeared circa 30,000 years ago (max).
