Definition for neutralization should be : A non-redox reaction between an acid and base, where these acid and base can be Arrhenius, Bronsted Lowery, and Lewis acid or base .
For your reaction, CaCO3 is an Bronsted Lowery acid and HNO3 is a Bronsted Lowery base, so their reaaction is neutralization.Whether CO2 is
formed is not important.
Bronsted Lowery acid : A proton donator
Bronsted Lowery base: A proton accepter
Lewis acid : A electron acceptor without changing its oxidation number
Lewis base: A electron donator without changing its oxidation number
Arrhenius acid : A chemical that will give H+ when dissolved in water
Arrhenius base: A chemical that will give OH- when dissolved in water
A chemical can belongs to more than one type of acid or base
e.g. H2O is a acid and a base. It act as acid when donate proton while act as base when accept proton.
H2O +H2O -> H3O+ + OH-
donate H+ accept H+ after accept H+ after donate
NH3 +BF3->NH3BF3 is also a neutralization.
NH3 is a Lewis base, while BF3 is a Lewis acid.
Your definition can be found on some CE textbook but it is not correct.
My definition is just a conclusion from my obsevation on AL chem reaction and definitions, but may be not exactly correct.
