No you can't with parameters you've brought forth.
Similar date codes mean nothing.
Get them tested on a good tube tester for transcconductance and then in an amp or other piece of equip that will put them at working voltage, for current draw.
If those two tests put the tubes within 5-10% (varies according to opinion) of each other, then you can call them "matched".
