Yes. Its possible. Especially when the mesh doesn't have midside node. You can check it under mesh section of analysis. There are three options for midside node;
Go to Mesh->Defaults->Element Midside Nodes-> Program Controlled/Dropped/Kept
If you dont have any element or node number limit problem, you should activate the midside nodes (Kept).

if you also use tet it is possible because one of the node is shared by many elements so in that case the size of elements may increase and gets beyond node numbers.
