No, you cannot install two standard master Lutron Maestro dimmer switches together on the same multi-location 3-way circuit. Standard electronic Maestro dimmers are designed with specific master circuitry that cannot be wired in parallel. Instead, if you want multi-location control (controlling one light from two different wall locations), you must install one Maestro master dimmer combined with one or more compatible Maestro companion accessory switches (such as MA-R or MSC-AD). Verification: Check the wiring diagram in the installation manual to ensure you are pairing a master unit with approved accessory companions.
