Wow, that's great topic. I don't know if there can be a Noahide Muslim, but I can definitely say that there were Muslims in history who were very good to the Jews. For example, Suleiman the Magnificient, the Sultan of Ottoman Empire.
Here is a quote from
http://en.wikipedia.org/wiki/Western_Wall-----------------------------------------------------------------------------------------------------------------------------------
In 1517 the Turkish Ottoman Empire under Selim I conquered Jerusalem from the Mamluks who had held it since 1250. The Ottomans had a benevolent attitude towards the Jews, having welcomed thousands of Jewish refugees who had recently been expelled from Spain by Ferdinand II of Aragon and Isabella of Castile in 1492. Sultan Suleiman the Magnificent was so taken with Jerusalem and its plight that he ordered a magnificent fortress-wall built around the entire city, today's Old City wall.
There are various accounts of Suleiman's efforts to locate the Temple's ruins. Rabbi Eliezer Nachman Puah, (ca. 1540), relates:
”I have been told that in the day of Sultan Suleiman the site of the Temple was not known and the Sultan had every corner of Jerusalem searched for it. One day the man in charge of the work, despairing after much searching and inquiring in vain, saw a woman (Arab woman - Spectator) coming with a basket of rubbish and filth upon her head. He asked her: “What are you carrying on your head?” – And she replied: “Rubbish.”
“And to where are you carrying it?”
“To such and such a place.”
“Where do you live?”
“In Bethlehem.”
“Is there no dunghill between Bethlehem and this place?”
“It is a tradition among us that whoever takes a little rubbish to that place performs a meritorious act.”
The curiosity of the officer was aroused and he commanded a great number of men to remove the rubbish from that place…and the holy site was revealed. When the Sultan learned of this, he rejoiced greatly and ordered the place to be swept and sprinkled and the Western Wall washed with rosewater...”
In the second half of the 16th century, Suleiman the Magnificent gave the Jews rights to worship at the Western Wall and had his court architect Sinan build an oratory for them there.
