They're both about getting results.

Serious.  What you learned as "calculus" was earlier called
"the analytic calculus" or "the differential and integral
calculus".  It's about getting results (very roughly speaking)
that have to do with "smooth" properties (of shapes and motions,
let's say).  

Lambda is entirely different--except that it's also a calculus,
that is, largely expressible algorithmically.  Lambda happens
to be about computations.

There are other calculi--"quaternion calculus" and "vector 
calculus" are two not-too-uncommonly-heard ones.  Lambda and
the one you learned in college courses are much the most often
used in such references.
