Hi.
Illustrator "should" open inkscape svg-s without any problem. Inkscape svg is a valid svg format with some inkscape specific features, like custom background colour, guide lines and the layer system.
Differences might appear at how illustrator deals with filters.
So while he should be able to open your svg file, the resolution is the only thing you may have to second check.
Illustrator works at 72 dpi while inkscape switched to 96 dpi. Meaning, if your image was drawn with px sizes in mind, an illustrator px is larger than inkscape's in physical units.
No worries though, just make sure the image is in the right size in mm/inch.
If necessary at all, because scaling an image in illustrator shouldn't be a big deal either.
