We can speculate on any possibility. The basis of science, and the reason for its outstanding success, is the requirement for evidence. Do we have any evidence of any other organisms ever doing anything of the sort? The answer is no.
Almost all known non-human tool use is for obtaining food, afaik.
Other primates use tools, but it's on the level of a stick stripped of leaves to poke into a termite nest (termites crawl on stick, remove stick, eat).
Avians are the other main category; some only have been observed using tools in captivty. Corvids (crows, ravens, rooks) are particularly interesting. New Caledonian Crows will actually bend the end of a tool to make a hook, good for prying out grubs from under bark. Rooks have handled some particularly complex problems in captivity.
There is no evidence of any non-human doing anything like making axes, chopping wood, and constructing something. If I understand the paper correctly, the 'axes' were 'handaxes' - archaeologist-speak for an unhafted axes, i.e., axes sans handles, i.e., effectively just the axe head which you hold in the palm of your hand. Our ancestors took > 2 million years to figure out how to attach tools to hafts, succeeding by ~200,000 years ago (but only in one place - 'the future is here, it's just not widely distributed yet'.)
