Dry tantalum capacitors (tantalum electrolytics) don't degrade over time like aluminum electrolytics do. IF the outer coating is intact you don't need to replace them. They are very reliable when applied correctly and explosive when not. 1. Failed or cracked coatings allow moisture to enter the dielectric.
A factor of 2 in value is unlikely to be relevant. Capacitors in some cases can have tolerances of +100% / -50% (wet aluminium electrolytic) but may be +/-5% or 10% or 20% for Tantalum. Warning: NEVER use tantalum capacitors in a "high energy" circuit where voltage can EVER exceed the voltage rating of the capacitor.
All tantalum caps fail shorted. That's the biggest problem with them. Aluminum electrolytics with low esr, like ones for smps, will work well as replacements. Just look at the application area. If they are power supply bypass caps no problem. Aluminum electrolytics will work fine.
Warning: NEVER use tantalum capacitors in a "high energy" circuit where voltage can EVER exceed the voltage rating of the capacitor. Even the shortest spike (sub microsecond) can puncture the oxide layer and "away it goes". Almost as much fun as a LiIon battery!. Related: electronics.stackexchange.com/questions/9120/…
When replacing tantalum caps with aluminum ones, keep in mind that the ESR depends on temperature. This especially gets a problem for low temperature where the ESR goes up. For the modern Al electrolytic caps there are also 3 types: classical ones with high ESR, low ESR and polymer caps.
Also, if one use ceramic instead of tantalum, it's generally safe use lower value (like 10uF), but one need to check datasheet. True, but soldering those huge-value ceramic capacitors is a problematic operation.

Can Tantalum caps be used to replace electrolytic caps
Tantalum is often mined in war countries, so that''s bad. Tantalum capacitors also have problems with over voltage, they can blow up or burn all of the sudden, with real nice flames. The ESR is typically higher than ceramic capacitors and even some polymer capacitors.
vintage tantalum capacitor replacement
In any case a 100uF 63V 105C capacitor will replace any 10,22,47uF tantalum capacitor on a power rail with no problems, it will fit, and will have similar low ESR and a long life.

Identify the Capacitor Type: Identify whether the capacitor is electrolytic, ceramic, or tantalum, as the replacement process can differ. Replace the Capacitor: If the capacitor is severely leaking or damaged, the best solution is to replace it with a new one.
Capacitor Questions
Tantalum capacitors increases distortion because the capacitance alters with (a) applied DC bias voltage, (b) applied AC voltage, and (c) frequency; the effects are consequently non-linear (higher on one side than the other) and thus harmonic distortion. The THD of a tantalum capacitor exceeds that of ceramics, which are awful.

Which type of capacitors to use in which setting?
Those Sanyo capacitors are special electrolytics, called OS-CON or solid polymer capacitors. They have special properties, that''s why people (including me) prefer to use a film capacitor to replace them. If not, I''d use a new OS-CON or a low leakage- low esr electrolytic.
