Can QSFP-DD 400G transceiver be used directly in OSFP ports?

No. QSFP-DD and OSFP are two different form factors with different physical dimensions. OSFP is slightly larger than QSFP-DD and cannot be directly adapted.

Can I interconnect a QSFP-DD 400G SR8 module at one end and an OSFP 400G SR8 module at the other?

Yes, QSFP-DD and OSFP only describe the physical form factor of the module. Both modules are 8x50Gb/s modulated and can be interconnected using multimode MPO/MTP 16 APC patch cords.
