No, these functions serve two different roles:

can_eventually_build_improvement() is meant to test if a city will ever be
able to build an improvement.  Never mind if a prerequisite building has
been built, or if the tech has been researched yet -- just return 1 iff
the city can -eventually- build the improvement.

could_build_improvement() tests if a city can build an improvement *right
now*.  This function tests if prerequisite improvements (such as a library
for a university) exist, if the tech exists now, etc.
