mIRC doesn't allow creating & as binvar name in some places, but once it's created, it won't always permit using it as a parameter. This means you can't use $bvar(%var) or $bvar(%var,0) to guarantee that %var contains name of a binvar that works with a particular command. It seems /bwrite and $regsubex are the exceptions to identifiers accepting it and commands rejecting it.
This is different than the issue where you can create a variable named % but not echo it, because every command and identifier using a binvar is either a command specifically for usage by &binvar only, or is an identifier where it's either not ambiguous whether & means binary not text, or it uses a switch to indicate that & means binary. i.e. 5th parm of $regsubex always begins with % or $
//set % test | echo 3 -a % [ % ] | echo 4 -a $var(%,0) $var(%,1) $var(%,1).value
The regsubex issue might be related to being an exception where square braces are normally allowed to touch commas and parenthesis, but the 5th parm won't accept without the spaces
bug: //tokenize 32 &v | echo -a $regsubex(foo,abc,,,[ $1 ]) $bvar(&v,1-).text
ok:: //tokenize 32 &v | echo -a $regsubex(foo,abc,,, [ $1 ] ) $bvar(&v,1-).text
Using binvar named & :
works: $hget yes $bvar yes
//hadd -m table item abc | echo -a $hget(table, item, &) - $bvar(&, 1-)
(repeating the $hget again, showing that once the binvar named & is created, that other commands don't always accept it)

//hadd -m table item abc | echo -a $hget(table, item, &) - $bvar(&, 1-) | bcopy &test 1 & 1 -1 | echo -a $bvar(&test,1-)
