Is the reaction between baking soda and vinegar a combustion reaction?

No. Combustion is an oxidation-reduction reaction; the reaction between baking soda and vinegar is an acid-base reaction followed by the dissolution of a gas.

HOAc + NaHCO3 --> NaOAc + H2CO3

H2CO3 --> H2O + CO2(gas)

Here, "Ac" is an abreviation for acetate, CH3CO2.
