You can select which page is opened, but you cannot edit more than one
page at once.

I have to admit that I don't know why removing the manual kerns does not
work sometimes. I mostly use inkscape's PDF import to get at some vector
graphic that is important for me.

OK, then you need another approach. What might work in a reasonably
scalable way is to distill the PDF into another PDF while removing all
the embedded fonts. Then your PDF viewer should choose a suitable
standard font as a substitute (probably also Tahoma) whenever you open
the new PDF file.
Here is an extremely quick-and-dirty, I-guarantee-for-nothing (!) bash
script to remove embedded fonts. It takes only one argument, the name of
the original PDF file, and it generates "...-NOFONTS.pdf". I only tested
this on one PDF file that I happened to have lying around, so I have no
idea how robust this is:
#! /bin/bash
TEMPPSFILE="${1%.pdf}-TEMP.ps"
FONTS="$(echo $(pdffonts "$1" | awk 'NR>2{print "/"$1}'))"
echo ".setpdfwrite <</NeverEmbed [$FONTS]>> setdistillerparams" > "$TEMPPSFILE"
pdftops "$1" - >> "$TEMPPSFILE"
gs -q -dSAFER -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -o "${1%.pdf}-NOFONTS.pdf" -f "$TEMPPSFILE"
rm "$TEMPPSFILE"
