Maybe, it’s hard to tell from the low quality image (not knocking OP here).
But original Grond usually has flames coming out the head of the mace in most artwork I’ve seen, and I cannot see it there. Morgoth also tends to have large pauldrons spikes and his crown often has more than 2-3 spikes coming out of it (but some images do show 3 large spikes, others have many more).
That said you can also find huge variety in his depictions across many different artists, and it’s not like there is a massive style difference between him and Sauron - Plus Sauron being a shapeshifter also makes it harder to definitively tell them apart as he has no set image or appearance.
Edit: Was looking this up and found the image on theTolkien forum - Apparently the battlefield depicted shows Sauron overlooking his Orc army at Gorgoroth
