I have a similar question. How do you test if the field in question
isn't NULL or '' (empty string)? Is the LENGTH a good test or is
there a better way?

I believe this is the equivalent statement you wanted:
SELECT
fieldOne,
fieldTwo,
IF(CHAR_LENGTH(fieldThree)>0,fieldThree,fieldFour) as Company
FROM table;
