I've heard it said many, many times that modern economics lumps land and capital together when considering the factors of production. Is this true? Are the considered the same?

In some introductory economics courses maybe but for the general field that hasn't been true since  the second edition of Wealth of Nations. Even Adam Smith decided to separate them really quickly. 

The factors of production are Land, Labor, Capital.

Then entrepreneurship/knowledge/informed willingness to take risks is the fourth factor but this definition is not very well accepted. But to answer your question, no economics does not lump land and capital together.
