Good question. I think perhaps not. This work is based on the data Gaia delivered in its most recent data release; the third so far. Only that release has provided both tangential and radial velocity of stars, which are crucial figures to compute the orbits of the binaries. This was done by correlating data collected simultaneously from the three instruments onboard Gaia. Does Euclid have the same three instruments or their moral equivalent? Will they operate Euclid such that they'll be producing similar data? I don't know. Even if there are equivalent capabilities, it's a different instrument, so the data will not simply slot in as the next tranche of observations.
