can i use?
Yes, or K-1 (kerosene).

I know. You aren't on automatic delivery and if you run out, what do you
do?
Keep a couple of 5 gallon cans around...

Yes, essentially the only differences between the #2 heating oil in your
tank and the #2 diesel at the pump are the transportation fuel taxes you
pay at the pump and the red dye they put in the non taxed heating oil.
Otherwise they are interchangeable functionally, and the heating oil is
also known as "off road diesel" since it's legal to use in off road
equipment.

It is a little more complicated than that. Diesel fuel typically is sold
as "diesel fuel" not a particular # oil. If the diesel fuel is sold in a
freezing climate a certain percentage of #1 is mixed in to minimize fuel
gelling effects.

People who have outdoor fuel oil tanks have the same jelling problems as
vehicles, I would assume that winter heating oil in cold climates is
"adjusted" similarly to vehicle fuel.
In this area #1 heating oil is thin, probably mostly kerosene and used in
"heaters" that don't pump the oil into the combustion chamber, #2 heating
oil is thicker and used in fuel oil burners. Diesel oil is rated as #2
diesel for use in engines and #1 version of diesel oil is jet fuel grade.
