Yes. A QSFP (40G or 100G) module can be inserted into an OSFP port by using a simple, completely passive, mechanical adapter. This adapter is available from Arista, with part number ADPT-O-Q-100G. The adapter and the adapter with a QSFP plugged into it, are shown below.

When using a QSFP module in an OSFP port, the OSFP port must be configured for a data rate of 100G (or 40G), instead of 400G.
