Yes, but... I have some suggestions.
1: Make backups of both files. (Just in case)
2: Create GEDCOMs from both files. (Export)
3: Create a NEW file, give it any convenient name.
4: Import each of the two GEDCOMs into the new file.
5: Use Match/Merge (carefully) to eliminate duplicates who were in both original files.
And you're done.
P.S. I'm going in the opposite direction; splitting my one file into several.
