The easy way is to type ⩽ (0x2A7D) instead of ≤ (0x2264) :). You can do
something like

\setuplabeltext [en] [lessthanequal={\leq}]
\setuplabeltext [pl] [lessthanequal={\leqslant}]

\def\le{\labeltext{lessthanequal}}

and then use \le, but I am not sure if this is a good thing to do.

Do you want \tan to produce tg? Again you can do

\setuplabeltext [en] [tangent={tan}]
\setuplabeltext [pl] [tangent={tg}]

\definemathcommand [tan]     [nolop] {\mfunction{\labeltext{tangent}}}

Same as above.

It is relatively easy to do this. I am in favour of implementing the
trignometric functions, etc; but I do not think that changing the meanings of
mathematical symbols is a good thing. It is really hard to remember the names of
symbols as is, changing meaning according to language will make it extremely
difficult.

Don't know.

\setuplabeltext [pl] [section={{},{.}}]

\setuplabeltext
