This is the right next step. Be sure to look at and compare all of the key dimensions...
1. C-T-C Top Tube length, which you've covered.
2. C-T-T Seat Tube length, relative to how long your seat post will need to be.
3. Head tube height, to get an idea of where your bars will fall in relationship to your saddle height so you can get an idea of how much rise your bars / stem will need. Given that the steerer is already cut on the tandem's fork, this is one you'll really want to pay attention to.
4. Standover height... shouldn't be a problem, but always good to check just the same.
5. Crank to front wheel axle, relative to toe clearance / overlap. Smaller tandem frames tend to have less toe clearance so, once again, this is a dimension to look at so that you don't find yourself surprised by having a minor overlap condition.
