Is it “legal” to have the base level and the max level to be equal, essentially eliminating the effect of mip mapping without having to change the filter.

EDIT : just re-read your question. I misunderstood what you were asking.
Yes you can set base and max levels to the same value. That’s basically “turning mipmapping off”.

It’s definately possible.
Taken from the specification at http://oss.sgi.com/projects/ogl-sample/registry/SGIS/texture_lod.txt :
Mipmap Completeness -------------------
The GL Specification describes a "complete" set of mipmap image arrays as array levels 0 through p, where p is a well defined function of the dimensions of the level 0 image. This extension modifies the notion of completeness: instead of requiring that all arrays 0 through p meet the requirements, only arrays 0 and arrays BASE_LEVEL through MAX_LEVEL (or p, whichever is smaller) must meet these requirements.
