If lymph nodes were clear and a typical lung carcinoid was removed stage 1 can it have gone to the liver?

Unlikely, however...: A true typical lung carcinoid stage i that was fully taken out by surgery has very low chances of spreading. However, it is still possible for it to spread, specially if it was not staged appropriately. Sometimes not enough lymph nodes are removed or a metastasis were already in other parts of the body but couldn't be seen with cts or pets. Thats why is important to follow up. Best wishes, ariel.

Yes: As noted, the correct staging at time of surgery and at time of tumor review by pathologists are critical. Modern classification of carcinoid has become far more sophisticated. Unfortunately, the nomenclature carcinoid is often deceptive and improperly used term. http://goo.gl/mxuzs.

Highly unlikely: Typical lung carcinoids grow very slowly, the slowest on average of all lung cancers. And they metastasize late in their development. For a stage I (less than 3cm by definition) typical lung carcinoid to have metastasized to the liver before spreading to any local or regional lymph nodes is highly unlikely. And Lung carcinoids are more likely to metastasize to bone, GI carcinoids go to liver.
