Um, no, I got confused and was talking about baritone scale, not DGBE on tenor scale, so I've deleted my post. If my rough calculations are correct, I wouldn't recommend using the middle four guitar strings on a tenor if you want higher tension in G tuning. Consider that a tenor is roughly a third of a guitar's scale: a tenor nut comes in a bit above the guitar's 7th fret. So using the same tension, the strings at that length would produce pitches over a fifth above the guitar's: low to high, B E A D F# B (but a little sharper). Comparing your target pitches (D G B E) to the middle four pitches, you'd have to lower the tension, like down-tuning by over a whole step, the very opposite of what you intend.
I couldn't speak to whether using high-tension or extra-high tension guitar sets would adequately compensate to give the result you desire (and whether using extra-high-tension sets would be safe). Added to which, not all "normal" guitar strings are designed for the same tensions. When Booli ran figures for a couple of tunings, it turned out that with different brands of guitar sets you'd want to use different string re-mappings, sometimes shifting over, sometimes not. Sadly, the simplest solution is to get out charts of string tensions for various guitar sets, then start crunching figures. In other threads on similar topics, Booli several times linked to a handy string tension calculator on the D'Addario website, so rummage about there.
As kissing said, most tenor bodies are really too small to adquately resonate well down to low D, so although I do like linear C tuning on tenors (which go as low as reentrant G ones) and even keep a tenor in linear Bb tuning, I myself wouldn't bother with linear G tuning on a tenor. (I do have a concert in viola fifths tuning, which goes down to low C [!] but not without a clear sacrifice in tone.)
