This is OK if you are running lights and converter only. Definitely not OK for AC. Running high current items on an undersized extension can cause a fire.
As an analogy if you are trying to move a large object and you are using a 3000lb capacity chain that is not long enough. If you add a 1500lb capacity piece of chain to it to lengthen it, the strength of the chain is now less than 1500lbs.
You may eventually need an extension that can carry 30A so why not just get it now and be safe.
